REGULATOR FoR GAS AND WATER.

SPECIFICATION forming part of Letters Patent No. 292,536, dated January 29,?1884.

l Application filed April 13.18513.v (No model.)

To all wiz/0m, t may concern: e

Be it known that I, ABRAHAM E. CoHN, a citizen of the United States, residing in the city and county of Philadelphia, State of Bennsylvania, have invented anew and useful Improvement in Regulators for Gas and Water, which improvement is fully set forth in the following speeification and accompanying drawings, in which- Figure 1 is a front view of a regulator enibodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a top View thereof;

Similar letters of reference indicate corresponding parts in the several figures.

My-invention consists of a device for regulating the amount of gas or water entering a meter or service-pipe, the construction and advantages being hereinafter fully set forth.

Referring to the drawings, A represents a quadrant, formed of metal or other durable material, having a graduated peripheral rim, c, and an opening, b, at the place from which the periphery is described. Projecting rearward from the quadrant, at the sides of the opening b, are lugs B, which are adapted to eircurnscribe the cock of a gas or water pipe, as shown in dotted lines, one of the lugs B having fitted to it a screw, C, for tightening the quadrant on said cock. A screw may, however, be provided for each lug, if desired or required.

D represents a key or lever, which has a boss, c, for engaging with the plug ofthe gas or water cock, said boss having a screw, E, whereby the key or lever may be tightened on said plug. The portion ofthe quadrant within the peripheral rima is cut4 away, forming a circular slot, d, and the adjacent portion of thel lever D is bent and passed through the slot, so that the handle end of said lever is behind thev rim c. To the bend e of the lever is firmly secured an'index or iinger, F, which appears on the front of the peripheral rim and sweeps over the graduations thereof. ,i

'The operation is as follows: The lugs B are applied to the cock of the pipe so as to straddle the same, and the screw C is tightened, whereby the quadrant is securely held in position. The lever D is now fitted to the plug' of the cock and the screw E tightened thereagainst, whereby said lever is securely held in position, the index Fand end of the lever being located ashas been stated. The lever may now be turned so as to open or shut the cock to partial or entire extent or intermediate portions,lit being evident that in the caseof gas the pressure ofthe samemay be regulated with lnicety, whereby the meter may register with more correctness, and whenthe gas is entirely shut off leakage within the house and registration of the escaping gas are avoided.

In the peripheral rim of the quadrant is a row of openings, f, into either of which may be placed a pin, G, wherebythe extent of motion of thelever D may be limited with certainty-a feature'important where gas is raised and lowered at different times, as in halls, places of amusement, churches, 8vo.

It will be seen that the regulator presented is simple, inexpensive, and easily applied and removed. In practice the key or lever D, being removable, has its boss c adapted to t the head of the screw C, thus serving as a wrench for tightening andloosening thelatter, whereby when one changes his residence he may disconnect the regulator and afx it without difficulty to the new locality, no special tools or appliances being required therefor, there being no interference with the service-pipe or meter or change in the arrangement thereof.

As.only the index F appears on the face of the quadrant, the graduations thereof appear to the best advantage, being unobscured.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isi l. In a regulatorfor gas, 8m., a quadrant having a circular row of openings and thekey or lever operating the plug ofthe cock, in combination with a removable pin, G, substantially as and for the purpose set forth.

2. A regulator for gas, &e., consisting of a quadrant with a graduated rim and attachinglugs, a securing-screw, a lever or key, an index, and a removable pin, said leve'having its handle end and the connected index on op'- posite sides ofthe rim of the quadrant, and said rim having a circular row of openings for said pin, substantiaily as and for the purpose set forth.-
